No matter what type of coolant is used, it becomes ineffective when allowed to become hot. 15š F. over room temperature is the maximum allowable increase in coolant temperature.
IF HOT -- IT'S NOT A COOLANT
Large coolant tanks with a minimum of sludge and a maximum of clean, low temperature coolant are important for an efficient wet grinding operation.
HEAT IS AN ENEMY OF PRECISION GRINDING
When attempting to maintain close tolerances, the temperature of the system must be controlled.
Heat causes:
- Poor Size Tolerances
- Poor Finish and Surface Condition
- Burning
Due to:
- Part Expansion and Distortion
- Spindle Expansion
- Excessive Abrasive Breakdown
The correct coolant temperature and proper abrasive specification are important for maintaining a cool cutting, precision abrasive operation.
